Is STL vector thread safe?

Is STL thread-safe?

The SGI implementation of STL is thread-safe only in the sense that simultaneous accesses to distinct containers are safe, and simultaneous read accesses to to shared containers are safe.

Are vectors thread-safe?

Vectors are synchronized. Any method that touches the Vector ‘s contents is thread safe. ArrayList , on the other hand, is unsynchronized, making them, therefore, not thread safe.

Is vector empty thread-safe?

There is no thread-safe guaranty on anything in the containers and algorithms of the the STL. So, No.

Is C++ std::vector thread-safe?

Therefore all classes available from the standard, e.g. std::vector<>, can safely be accessed from multiple threads in the same manner.

Are C++ containers thread safe?

He asked for facts: “Do C++11 versions of STL containers have some level of thread safety guaranteed?” The factual answer is “Yes,” because the standard does have some level of guarantees.

What are the types of STL containers?

The three types of containers found in the STL are sequential, associative and unordered.

How do I make a vector thread-safe?

Vector methods are all synchronized. So using it from multiple threads is “safe”. You only need to synchronize if you need a read-evaluate-write process to be atomic. Synchronizing your own methods does not necessarily make your code thread-safe for those scenarios.

Is LinkedList thread-safe?

Not Thread-safe: LinkedList is not suitable for concurrent access.

Which data structure is thread-safe?

The collection classes that are thread-safe in Java are Stack, Vector, Properties, Hashtable, etc.

What are concurrent vectors?

A concurrent vector system is a set of two or more vectors whose lines of action intersect at a point. It is not necessary for all or any of the vectors to be actually in contact with the common point.
